The Allen Bradley 20-750-APS is an auxiliary power supply module designed for PowerFlex 750-Series AC drives. It provides external control power to the drive’s control circuitry, communication modules, and HIM interfaces without energizing the main power section of the drive. This functionality allows technicians and operators to configure, diagnose, and maintain the drive safely while the main input power remains disconnected.
Engineered for industrial automation environments, the 20-750-APS enhances maintenance efficiency, simplifies commissioning, and improves system accessibility in applications where uninterrupted control-level access is essential.
